The event is the southeast's premiere show devoted to model trains and "railroadiana" -- which means vintage railroad artifacts including signage and lighting. More than 300 vendor and exhibitor tables are expected for the 50th show, with many selling rare and collectible artifacts and model train cars -- and several groups will have model train sets displayed and running for visitors to watch. The 50th Atlanta Model Train and Railroadiana Show takes place Saturday from 9 a.m. to 4 p.m. at the North Atlanta Trade Center on Jeurgens Court in Norcross.

Good Day Atlanta's Paul Milliken spent the morning there, getting a preview of this year's show.
